Mitsubishi CNC | M60-M70-M80 Series | Spindle Orientation Parameters


Introduction

In case of encountering orientation problem, the parameters needed to overcome the problem are as follows. Spindle orientation parameters are different depend on controller brand or series.

CNC Spindle M19 Orientation

Spindle Orientation Control

M60 Series

# 3025 Enc_on: If this parameter is 1, the machine has only PLG.
If this parameter is 2, the shaft side encoder or second PLG sensor. With set to 2, orientation is provided by the second encoder or the second PLG sensor.
# 3237 Bit 0: This parameter should be set to “1” if there is a proximity switch used for M19. It is usually set by the manufacturer.
# 3207: With this parameter, we adjust the position of the spindle motor.
(Value can be entered from 0 to 4096)
After entering value, machine is reset and the position is checked again by M19.
# 3021: Orientation speed.

M70/M700/M80/M800 Series

# 3106 Bit F: This parameter is set to “1” if there is a proximity switch used for M19 (8xxx).
# 3108: With this parameter, we adjust the position of the spindle motor.
(Value can be entered between -35999 and 35999).
After entering value, the machine is reset and the position is checked again by M19.
# 13225: If the proximity switch is present, set to 20. (Bit 5=1)
# 13227: If the proximity switch is present, set to 4000. (Bit E=1)

Things to Know

  • To check new setting, we must press the Reset button on the machine and command M19. Otherwise, the machine will not make an orientation since it is already in the M19 position.
  • After setting the position, do not command tool change directly, we must move the tool change arm manually to make sure that the spindle harmonize with tool change position (G28, G30 etc…) for Z axis. Misconduct can cause accidents and injuries.
  • Sensors and encoders connected to the spindle system can be controlled from the connectors on the spindle drive. If both encoder connectors are connected, the machine is operating in closed loop mode. Second encoder directly on the shaft side. If only one connector, the machine is semi-closed. So there is only an encoder back of the motor (internal).
